Subject: [PATCH v2 0/5] Add Intel VT-d nested translation
Date: Thu, 9 Mar 2023 00:22:02 -0800 [thread overview]
Message-ID: <20230309082207.612346-1-yi.l.liu@intel.com> (raw)
This is to add Intel VT-d nested translation based on IOMMUFD nesting
infrastructure. As the iommufd nesting infrastructure series[1], iommu
core supports new ops to report iommu hardware information, allocate
domains with user data and sync stage-1 IOTLB. The data required in
the three paths are vendor-specific, so
1) IOMMU_HW_INFO_TYPE_INTEL_VTD and struct iommu_device_info_vtd are
defined to report iommu hardware information for Intel VT-d .
2) IOMMU_HWPT_DATA_VTD_S1 is defined for the Intel VT-d stage-1 page
table, it will be used in the stage-1 domain allocation and IOTLB
syncing path. struct iommu_hwpt_intel_vtd is defined to pass user_data
for the Intel VT-d stage-1 domain allocation.
struct iommu_hwpt_invalidate_intel_vtd is defined to pass the data for
the Intel VT-d stage-1 IOTLB invalidation.
With above IOMMUFD extensions, the intel iommu driver implements the three
callbacks to support nested translation.
Complete code can be found in [2], QEMU could can be found in [3].
